Decanter vessel and pouring spout

Abstract

A decanter vessel including a rigid flask formed with an upwardly projecting neck terminating in a circular edge. Received over such neck is the annular skirt of a pouring spout unit. Such skirt being formed with a frusto conically shaped interior and including on its inner wall a set of inwardly face and upwardly angled ratchet teeth spaced from the neck to form an annular cavity. Received in such annular cavity is a locking ring, such ring having ratchet teeth formed in its exterior for engagement with the first mentioned set of ratchet teeth. The ring is contractible radially inwardly such that, when pressed upwardly into the cavity will cause the wall of the skirt to press such ring radially inwardly against the surface of the neck to thereby entrap the neck within the pour spout unit.

What is claimed is: 
     
       1. A decanter vessel comprising; a rigid flask having an upwardly projecting neck terminating in a circular edge;   a pouring spout unit including an annular skirt for telescoping around the upper portion of said neck and an annular downwardly facing shoulder for overlying said edge, said skirt being formed with an interior wall of a generally frusto conical shape to angle downwardly and outwardly to form an upwardly tapered annular cavity between the neck and interior wall and being further formed on said wall with a first set of resilient ratchet teeth disposed about the periphery thereof and configured to angle upwardly and inwardly;   a locking ring formed to encircle said neck and be received in said cavity, said ring being compressible radially inwardly and being configured to, upon being driven upwardly into said cavity, be forced radially inwardly into gripping relation with said neck by the interior wall of said skirt, said ring being formed on its exterior with a second set of resilient ratchet teeth arranged to ratchet along said first set of teeth and to engage in locking relationship therewith;   whereby said ring may be installed in embracing relation on said neck and said pour spout unit positioned on said neck and said ring then slipped into said cavity to be pressed upwardly thereinto to compress said ring radially inwardly against said neck while engaging said sets of teeth in locking relationship to lock said ring in position engaged against said neck.   
     
     
       2. A decanter vessel according to claim 1 wherein: said neck is formed with a bead defining said edge; and   said ring is, upon engaging said wall and being flexed radially inwardly, engaged under said bead.   
     
     
       3. A decanter vessel according to claim 1 wherein: said ring is split to provide for expansion and contraction thereof.   
     
     
       4. A decanter vessel according to claim 1 that includes: an annular gasket interposed between said shoulder and said edge.   
     
     
       5. A decanter vessel according to claim 1 wherein: said shoulder is formed with a downwardly facing annular recess for overlying said edge.   
     
     
       6. A decanter vessel according to claim 1 wherein: said locking ring is formed in its exterior with a frusto conical shape to complement the shape of the interior wall of said skirt.   
     
     
       7. A decanter vessel according to claim 2 wherein: said ring is split to provide for expansion and contraction thereof.   
     
     
       8. A decanter vessel according to claim 2 that includes: an annular gasket interposed between said shoulder and said edge.   
     
     
       9. A decanter vessel according to claim 2 wherein: said shoulder is formed with a downwardly facing annular recess for overlying said edge.   
     
     
       10. A decanter vessel according to claim 2 wherein: said locking ring is formed in its exterior with a frusto conical shape to complement the shape of the interior wall of said skirt.   
     
     
       11. A decanter vessel according to claim 4 wherein: said ring is split to provide for expansion and contraction thereof.   
     
     
       12. A decanter vessel according to claim 4 wherein: said shoulder is formed with a downwardly facing annular recess for overlying said gasket.   
     
     
       13. A decanter vessel according to claim 4 wherein: said locking ring is formed in its exterior with a frusto conical shape to complement the shape of the interior wall of said skirt.
